The Fizz Saver, according to the 200+ customer reviews, is the worst thing that’s come to soda since RC Cola. It leaks, it breaks, the design is flawed… so what can you do if you drink 2-liter bottles of soda? Apart from the fact that the bottles come with caps, the similarly-named Fizz Keeper seems to do the job.
But let’s veer back away from cheap products that work, and check out the Fizz-Keeper Can Pump And Pour, a device that clips to the top of a 12-ounce soda can and lets you “save” it for 3 weeks. This would allow you to drink 0.57 ounces of soda a day, an implausible amount for any human to intentionally drink, of any liquid.
